Combining such devices into a multi-degree-of-freedom inertial measurement unit (IMU) on a single-chip enables the simultaneous measurement of pulmonary lung sounds, chest wall motion, heart sound signals, as well as of user body motion. The CMOS ASIC for the acoustic IMU consists of switched capacitor and transimpedance amplifier front-end circuits that utilize correlated double sampling and chopping for the dynamic cancellation of offset and flicker noise, and use charge injection calibration techniques to compensate for MEMS capacitor mismatch.\u202fFor tuning and alignment of gyroscopic resonators, low-noise high-voltage charge pumps are implemented on-chip. We discuss the prospects of reducing power while maintaining precision in interface ICs for MEMS IMUs and review a few IoT applications of these devices.\u0026nbsp;\u003C\/p\u003E\u003Cdiv\u003E\u003Cp\u003E\u003Cstrong\u003EBio:\u003C\/strong\u003E Farrokh Ayazi is the Regents Entrepreneur, and the Ken Byers Professor in Microsystems in the School of Electrical and Computer Engineering at Georgia Tech, where he has been a member of the academic faculty since January 2000.\u202f During his career at Georgia Tech, he has graduated 35 Ph.D. students and advised 22 postdoctoral fellows and research engineers. He is currently also the founder at StethX Microsystems, a spin-off of his research lab that is developing next-generation\u202fwearable devices for long-term monitoring of cardio-pulmonary diseases\u202fusing a proprietary microchip sensor technology.\u202f Prior to StethX, Dr. Ayazi was founder and CTO of Qualtr\u00e9, another spinout of his research lab that develops bulk acoustic wave gyroscopes for autonomous car and personal navigation systems, which was acquired by Panasonic in 2016.\u202f\u202f Dr. Ayazi\u202fis a fellow of IEEE and the National Academy of Inventors (NAI) and holds 70 patents.
